        The Hamming distance between two integers is the number of positions at which the corresponding bits are different.

        Given two integers x and y, calculate the Hamming distance.

        Note:
        0 ≤ x, y < 231.

        Example:

        Input: x = 1, y = 4

        Output: 2

        Explanation:
        1   (0 0 0 1)
        4   (0 1 0 0)
               ↑   ↑

        The above arrows point to positions where the corresponding bits are different.
